Helpful Comparison Short Insights

When evaluating the best ignition coil for 6.2 silverado, the most crucial factor is coil geometry and terminal type. The 6.2L V8 platform spans different generations, and the coils are not interchangeable.

• The UF-414 vs. UF-742/UF-743 Divide: If your truck is 2014 or newer, you will need either the UF-742 (Pin Terminal/Round) or the UF-743 (Square) style. If your truck is 2013 or older, you need the older UF-414 (Round) design. Confirming your coil shape before ordering is essential to avoid installation failure.
• Kit vs. Single Coil: The Round Ignition Coil Packs Spark Plugs (UF742) kit offers the best value for a full performance tune-up, as it includes the necessary spark plugs. This is the recommended choice for high-mileage trucks.
• The OCPTY 1-piece UF742 coil is excellent for emergency repairs or replacing a single, diagnosed bad unit, minimizing immediate costs.
• A-Premium offers sets for both modern coil types (UF-742 and UF-743), giving buyers reliable OEM-spec performance regardless of which coil design their 2014+ Silverado uses.

Final Verdict: Choosing the Right Power Source

Selecting the appropriate ignition coil for your 6.2L Silverado is straightforward once you know your truck’s generation and specific coil style.

For the Modern Truck (2014+ Gen V L86/LT1):
If you seek the absolute best value and a complete performance overhaul, the Round Ignition Coil Packs Spark Plugs (UF742) kit is the winner, providing eight coils and eight plugs. If your truck requires the Square Coil UF-743 variant, the A-Premium Ignition Coil Pack Set of 8 (Square Coil) is the top choice for reliability and complete replacement.

For the Legacy Truck (2007–2013 L9H/L94):
The clear victor is the ENA Round Ignition Coil Pack for UF414. This set provides the specialized fitment and voltage integrity required by the previous generation 6.2L engine.

For Targeted Repair:
When you only need a single replacement to get back on the road, the OCPTY Ignition Coil Coils Pack (1 pcs) is the highest quality single unit designed to match OE standards for the popular UF742 application.

Best Ignition Coil For 6.2 Silverado FAQ

Q1: How do I know if I have the Round Coil (UF-742) or the Square Coil (UF-743) on my 2014+ 6.2L Silverado?

This is a common point of confusion for Gen V 6.2L engines. You must visually inspect the coils currently on your engine. The UF-743 has a distinct square body profile near the mounting bolt holes, while the UF-742 (and the older UF-414) have a more traditional rounded profile. Additionally, the UF-742 coil uses a 4-pin connector, while the UF-743 uses a 3-pin connector. Always confirm the OEM part number stamped on your existing coil before purchasing.

Q2: What are the symptoms of a failing ignition coil on a 6.2L V8 engine?

The most common symptoms include the illumination of the Check Engine Light (CEL), often accompanied by codes P0300 to P0308 indicating cylinder misfires. Other signs include rough idling, noticeable loss of power or hesitation during acceleration, and poor fuel economy. In severe cases, you may hear backfiring or notice a distinct smell of unburnt fuel from the exhaust.

Q3: Should I replace all eight ignition coils at once, or just the bad ones?

While replacing only the failed coil will immediately solve your misfire, if your 6.2L Silverado has over 100,000 miles on the original coils, it is highly recommended to replace the entire set. Coils wear out due to heat and age, and once one fails, the others are likely to follow soon after. Replacing the full set ensures consistent spark energy across all cylinders, maximizing engine performance and reliability.

Q4: Does the type of ignition coil affect my 6.2 Silverado performance, especially when towing?

Absolutely. The ignition coil generates the high-voltage spark necessary for combustion. If the coils are weak or failing, the resulting weak spark leads to incomplete combustion (a misfire), which dramatically reduces horsepower and torque. When towing or hauling, the engine operates under high load, placing increased demand on the coils. Using a high-quality best ignition coil for 6.2 silverado ensures you get the full, advertised power output even under heavy stress.

Q5: What is the average lifespan of factory ignition coils on the 6.2L V8 engine?

Under normal driving conditions, factory coils typically last between 100,000 and 150,000 miles. However, factors like extreme heat, frequent high-load driving (towing), poor spark plug maintenance, and general electrical system fluctuations can shorten this lifespan significantly.

Q6: Can I install these ignition coils myself?

Yes, replacing ignition coils on the 6.2L Silverado is a relatively straightforward job for the average DIY mechanic. They are easily accessible on top of the valve covers. You typically only need standard socket tools, a torque wrench, and patience. The process involves removing the coil wire connector, unbolting the coil pack, and swapping in the new unit. If you choose a kit that includes spark plugs, you will need a spark plug socket and potentially a gap gauge.
